Appnationmea octber 2, 1920.` seriai No. 414,295;

T0 all whom it may concern: Y Be it known that PHILIP I-I. DoRsnY, a citizen of the United States, residing at Algiers, in the parish of Orleans and State Vof Louisiana, has invented certain new and useful Improvements in Cushion Iheels, of which the following' is a specification.'

The present invention relates to resilient wheels and more particularly to wheels of the spring wheel, type in which the tire is yieldingly supported about the hub by means of Connections including springs or equivalent means adapted to take up or absorb shocks received by the tire and prevent their transmission to .the hub andthrough it, to

y the vehiclebody.`

One ofthe objections to existingwheelsr of this type is that they are not sufficiently sensitive and, therefore, only veryfimperfy fectly absorb the. shocks. Another objection is the complexity `of the connectionsbetween the hubs kand tiresor outer wheel members. Affurther objection is the weakfk ing parts. .,An additional objection'to wheels of this type is the weakness of resistance to the side thrusts in making a turn or rounding corners., Among the forms ofthis typefinvolv-ing, the above objections is the formhavingv telescopic spoke sections, one section pivoted or otherwiseconnected at .one end to the hub and receiving the other section, while such other sectionis pivoted to'thefinnerface of ,they felly or tire, the spring or othershock absorbing element being disposed between them. The purpose of this inventionis to overcomej'these and other objections and provide a wheel of this type n,

which is simply,l constructedand may be `quickly inanufacturedat areasonable cost.

In order to more clearly,I disclosethe invention, a preferred form islshown in the accompanying drawings and -will be 'more ,fully set forthin the followingspecification and, claim, though itis clear. that many structural' changesvand changes in the `arrangementsloffvarious parts may be made withoutl in any degree departing from the field yand scope of the invention, ,and` it is meant to include'them within the scope of the appended claim.

y In thedraw`ingsz j Fig. l 1s a side elevation withthe casing removed from one half of the wheel, and` onehub element partly broken away, and

- Fig.v 2 is a cross section on line Vof Fig. l. l.

In thepresent wheel the tire comprises i the tread l clamped between the side ring plates 2, "which are kept in their spaced relation by the felly sections 3, between` which is held a connecting or driving ring 4. The parts 1, 2, 3, and 4 are all secured together to forma unitary structure yor tire by means of securing bolts 5 passing laterallyl through members 2,` 3, and 4. The

rings `2 are of considerabley width and eX- tend `considerably beyond the felly toward the hub." rIhe'i'nner face of each plate is beveled'or feathered toward the outerface toa considerablefdepthfand throughout the entire circumference as-at 100, for a purpose to lbe ylater disclosed. The hub comn prises two simple duplicate castings 6 each havingA a plurality of radially disposed oblongopenings or spring receiving pockets 7,

and each openingin turn has an inwardly eiitending radially disposed notch 13 fora purpose to be later disclosed.V In the outer circumferential vfaceof each casting and inline with thelongitudinal centre of each formed a small bore for a purpose to be later disclosed.v Withineach opening 7 and having a close sliding .fit between the wallsy thereof is a guide block 8 ,through the centre ofiwhich extends a post 9,. Each ool opening '7, and communicating therewith, ris

block is fixed to its post bya connecting pin lO in such manner that there can be no .relative motions between them. Disposed 4abcutf each post are two. coil springs l1U and 12, one arranged between. the block 8 andi the outer or circumferential ,wall .of

the opening `7., and the other between the block and the bottom or inner wall of they notch The springs are so'balanced as tol normallvkeep each block about midway n of the' combined length ofits opening 7v and .the notch y13, as will be readily understood.

vIn order to regulate the operating. force of each spring 12, for properly positioning vblocks `8, a small platelOl' is, used.; One of or obstructions met. Shocks thus received and partially dispelled are transmitted through the flexible connections to the absorbing springs, where they are practically entirely eliminated.

Although the hub has been shown as comprising two elements connected together, it is clear that it could be made as a single casting complete, or each element could have one of the face plates cast integral with the body portion, the other only, being separate. Likewise, the plates 2 may be made as several annular plates or rings, the inner one of the several parts, without in any mannerk departing from the eld and scope of the invention, and it is meant to include all such within the scope of the appended claim. n

Having thus described my invention, what I claim and desire to protect by Letters Pat-k ent is A resilient wheel comprising a hub-block provided with a series of pockets in combination with a series of compression' blocks slidablymounted in said pockets, a post carriedv by each block, resilient means acting oppositely on said compression blocks, a felly, a driving ring extending radially inward therefrom and disposed mid-wayrbetween the opposite sides of said felly, a plurality of spoke Sections alternately radially oppositely oii'set, pivotal connections between one end of each of said spoke sections and said drive ring, pivotal connections between the opposite end of each spoke section and one of the aforesaid posts, rings connected to said felly and extending radially inward and having their inner edges bevelled to provide clearance for they aforesaid spoke. section in their kflexing movements, annular casing plates slidably engaging said hub-block, each said plate being provided with a large central opening permitting' easy access to the hub ycap and end of the aXle while all parts of the wheel and casing are ink assembled relation, and connections between said casing plates and the aforesaid rings. v

In testimony whereof, I have signed my name to this Specication in the presence of two subscribing witnesses.
